In the previous numerical studies, interface-capturing capabilities were used to account for the surface tension forces in the absence of intermolecular forces (i.e., disjoining pressure). For static sheets, the disjoining pressure is neglected as the minimum computational cell is larger than the film sheet thickness in which the intermolecular forces will drive its perforation. Therefore, the hole formation is an outcome of the numerical cut-off interfacial length scale, i.e., minimum mesh size (\(O(10^{-6})\) m). Nevertheless, recent experiments [1]}, [2]}, [3]} demonstrate the existence of hole formation in dynamic sheets with a characteristic film thickness on the order of microns.
